Fan Motor Replacement Assembly
The fan motor in the Classic series utilizes sealed ball bearings that are subject to lubricant migration and oxidative thickening over time. As the bearing races develop microscopic pitting (spalling), the rotor loses concentricity, resulting in a 50/60Hz mechanical hum that resonates through the metal chassis. Replacing the integrated motor assembly restores the balance and eliminates the acoustic resonance caused by mechanical friction.
